I remember seeing someone a while back using actionscript a method to draw a pattern. I thought it was a really interesting take on as and kept in the back of my head for when the possibility came up.
View 1 Repliesi'm trying to search a string for a particular pattern, and replace it with elements from within the pattern... for example..here's the given string...if you want to learn how to use regexp, {url===http://somesite.com, text===click here}.
the pattern...
{url===http://somesite.com, text===replacement text}
and the intended result...
if you want to learn how to use regexp, click here.
of course, i'll extract the url and do something else with it... i'm just wondering what the regexp is for that pattern, and how i can extract things from the results returned.
I am using the draw() method of the BitmapData to encode a jpeg of part of the image. Now this should be easy enough given the object I want to draw to the bitmap is on the stage at design time so I know its location and dimetions exactly! Heres the code I have in place.
Code:
var myBitmapSource:BitmapData = new BitmapData ( street.width, street.height, false, 0x333333);
myBitmapSource.draw(street, null, null, null, new Rectangle( 96, 5, 571, 450 ), true );
I know for a FACT that no part of the street clip I am drawing out is in negative space, and it's registration is (0,0). However, it cuts off A lot of the top of my image. y=5 in the above rectangle is where I need the top to be, but it cuts the top off of the image... even if I change it to 0, it has no effect.
I'm making something that requires me to draw() the youtubeplayer Giving me this pretty error:

I'm trying to do some lean blitting for an object that rotates by rotating it once at startup and capturing a BitmapData snapshot of each 5 degrees. The problem I'm having is that the draw() method of the BitmapData object is only picking up pixels in the MovieClip that are below and to the right of the registration point. If I change the MC so that the registration point is in the top left corner, I sometimes get what looks like most of the pixels, but the entire object rotates into and out of the frame, since it's rotating around the corner and not the center.
View 5 RepliesI need to be able to draw a thick patterend line between 2 points in AS3, I can't use the draw API because it doesn't all me to actually put detail (pattern etc) into the thickness of the line, I thought about perhaps using the line to create a bitmap version and then using that as a mask, but I remember many years ago seeing some examples that use a movieclip as a source for a line.
View 1 RepliesI am having an issue with using BitmapData.draw(stage). I am getting the following error:
SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: file:///C|/Documents%20and%20Settings/bla...bla...bla.swf cannot access null. No policy files granted access. Here is a portion of my code:
var bd:BitmapData = new BitmapData(2800, 2100); bd.draw(stage);//this is where the error happens All of the files referenced (.xml/.jpg/.swf) are located in the same local folder as the main .swf. How do I get around this error? The main objective is to print the stage using PrintJob(). I am using Flash Professional CS5.5 and publishing to Flash 10.0/10.1. Let me know if I need to supply any more info.
i have a class thats create a class with bitmapData that merge 2 IBitmapDrawable. one of them is 24*20 while the other is 16*16.i want to draw the smaller first in a bitmapData object which its width and height are 24*20 but i want to draw it in the center of the big bounds.

I can't understand why should I even use the Singleton pattern in ActionScript 3. Can anyone explain me this? Maybe I just don't understand the purpose of it. I mean how it differs from other patterns? How it works? I checked the PureMVC source and it's full of Singletons. Why are they using them in the View, Module, Controller?
View 2 RepliesI'm working with some Action Script file and I found this:
var pattern:RegExp = /.*//

I know it's a regular expression and that exec() is looking for my pattern in my string. But how should I understand this pattern?
I am working on a Flash project that initially had a simple template for the animation, but has grown to have different "states" with multiple templates (not under my control)Because of this, my update (ENTER_FRAME) loop is now starting to look a bit like this:

switch (state) {
case "intro":
switch(layoutState) {

If I place a pattern or object over a 3d object created in CS4, will it affect it by warping it in any way.I'm looking for a way to push a pattern over a 3d object, for the pattern to look like the 3d object is "under" it.
View 2 RepliesI would like to create a repeating pattern using a bitmap from my library as a background. I would like the pattern to always fill the stage area when the brower window is scaled. The code below works, but I think it may not be the most efficient way to handle this. Seems to be a little slow.
function onResizeStage(evt:Event):void{
backGroundSprite.graphics.beginBitmapFill(pattern(0, 0));
backGroundSprite.graphics.drawRect(0, 0, stage.stageWidth, stage.stageHeight);
backGroundSprite.graphics.endFill();
}
How can I find a given bitmap pattern on a bitmap ( loaded jpeg )? Is there any flash classes / functions for this purpose?Here is the sample image and has 4 patterns.What I want is to get the bounding informations of the 4 patterns on the image ( x , y , width , height ).

View 1 RepliesI'm looking to get some good books on design patterns and I'm wondering what particular pattern you'd recommend for a Realtime Strategy Game (like Starcraft), MVC?. I'd like to make a basic RTS in Flash at some point and I want to start studying the best pattern for this.

View 1 RepliesI plan to have the swf fill the browser window, and this should work fine for that. When people click on a button, I want the view to "zoom in" by scaling to 200% and setting the x and y coordinates appropriately.How can I do this with the repeating pattern, because the way I have made it is a series of movieclips. Is there a better way to make it so it is just one movieclip I can control the scale and position of?
ActionScript Code:
tileWallpaper = function () {
tileWidth = 200;

I have a model which manages all of my data (DataManager)
I have a series of view classes, which manage stage instances.
I would like my view classes to listen for custom events within my DataManager class. So, for example, when all of my data files are loaded, I would like to have a custom event dispatch. All of my views will have listeners within them, waiting for events from the DataManager to trigger functions within.[code]...

I started 2 days ago programming in as3, so I'm building a website and I want to create a pattern for my background.The pattern is a bitmap image 300px X 300px and I want to repeat it along the x axis and y axis of my document.My stage is 1280 x 800)And I want also to have the pattern to fill all the screen in case of the user's screen become larger than the resolution of the stage that I'm building the website on.

View 2 RepliesI wanna ask about the usefulness of this decorator pattern.Decorator pattern allows user decorate an item with different unique things.But what if there are 800 items to decorate the main component?That would lead to 800 subclasses under abstract decorator.Would XML as database shine in this area?Whats the point of having decorator pattern in the first place when we could just use arrays and a storage for item information such as prices in XML?
Arrays can do all the things that decorator can do, and further more uses a few XML easier to manage compare to 800 classes, although its against the concept of "close for modification"

Is there some way in flex to parse strings to date. I want it to support custom formats similar to 'dateformatter'. Using 'dateformatter' class we can parse date object in various string formats as specified by 'formatString property'. I want it other way round, from string to date. The parse method 'Date.parse(my_string)' does string parsing but for a very limited set of formats. Can't we have something similar to following, where user can specify his/her own formats.
someformatter.formatString = 'HH::MM::SS' ;
mydate = someformatter.formatTodate('23::56:34');
Will 'parseDateString' method of dateformatter be useul here?
Right now, I've got a switch statement which is being used to create objects based on a string. There are three types of objects which extend an abstract generic object. I should really be using a factory pattern, which I'm figuring out right now. My issue is thus: flexibility of the factory pattern, but right now I'm storing the would-be products in special dictionaries dedicated to their type.
_type1[location] = ArrayOfType1s
_type2[location] = ArrayOfType2s
_type3[location] = ArrayOfType3s
